[Suggestion] Do the captured lair (wildling village, ogre lair etc.) spawns scale?

I find caputred lairs capable of spawning troops (wildling villages, ogre lairs etc.) very entertaining, they give FE much fantasy flavor and can even turn the tide of the game. But one question bothers me, do their spawns (wildlings, ogres) scale as the game progresses? I guess they do not and that is a pity. Cant we just let the lairs to to be upgraded (lets say 3 levels) and then produce higher tier units as well? It would be great if they can spawn also e.g. shamans (coal stones!), trolls, more powerfull ogres/dragons etc. - something like Ceresa has with the shard demons.

It is a missed opportunity here, not mentioning that deploying basic wildling warriors or ogres middle/late game is just joke...
