I'm going to supplement my "no" on the poll a bit.
I love playing as cavalry and actually on several maps being pretty useful.
But I can see how cavalry impact the bots' AI and for this reason I have voted against cavalry.
It is very possible to get sniped of your mount pretty soon, but it actually seldomly happens. When you get close enough entire regiments, it's possible to draw the attention of almost every bot around.
They still miss most of the time and if you're an experienced mounted combatteer, you can easily get 5-10 kills within moments.
Single experienced cavalrymen can easily distract entire platoons, inflict serious damage and hunt especially for commanders.
Fun as h-beep-, but it makes some games very unbalanced.
Plus, having suicidal attacking cavalry commanders also brings unwanted situations.
It's just silly to see individuals dodging all defenders for a single arty/engineer kill and get killed themselves almost immediately.
So I like it, but with "siege" in mind, I would seriously advice against cavalry.
Thanks for the input! 
I have to agree to your points myself as this is the very reason i didn`t enable cavalry to begin with! 
The thing is we need to test it and get as many people`s opinions on the matter to see what the majority want. I know for a fact that many maps are totally unsuitable for cavalry and will end up having them disabled. There are other maps where defenders have a far harder time due to the limited nature of their defences and where a few cavalry on their side could help a lot.
I have mostly (only) played as defender, but a single time as attacker made me view it all differently.
Especially on the map suitable for cavalry, the cavalry can really dismount assault. Just a single cavarly man charging/wounding some, will attract a complete group (if they were close to each other / in formation).
The only way I could actually get grouped bots together on the wall / inner boundraries, was by herding them each single foot. Just outside the walls and most bots would target cavalry, drawing them away from the flag.
This was on the snow covered map, with a village on both the right/left side; the left being elevated.
On the other hand, cavalry on the attackers' side (not the bots) is extremely useful, unless they are going kill hunting. (ie. charging defending sappers/artillery over and over again).
Quickly going to spots to move your bots to and retreating to cover, was the only 'sure' method of herding your bots inside. Being easy targets for cavalry, which they only target with a charge command and will most often go the wrong way.
It wouldn't be as bad if the bots knew how to react to cavalry, but they only really target them when getting ran over. A superior method of defending cavalry is to kill 2-3 bots in a single run and run all the way to the other side and repeat. Not the best cavalry myself, but doing this I was easily getting in the top 3-5 without losing all lives (which is hard as charging cavalry). The only way you die, is to get sniped or targeted by a commander, as the bots will not melee you spontaneously.
But my conclusion is a bit ironic. The maps, which are not really suitable for cavalry, are best with cavalry, as the bots wont get distracted too easily.
P.S.
Was just thinking about it.. and it's kinda strange to feel safe as cavalry charging into a defending line, which I often did. (as bayonets seem to be meant to go versus mounts)
