I haven't noticed a demand for this in our area but this may mean I've just not been aware of the need. There may be people who find our regular sessions off-putting and who'd prefer a slower or beginners' session. I suppose the answer is that if you'd like a beginners' session, ask around and see whether anyone is prepared to start one or set aside the early part of the evening for one. Ideally you want someone with some experience, so that they can point the newbies in the right direction to enable them to join in with established players.

I can see that one possible problem might be the venue - if there's a regular session in a public bar, and if the publican is providing a free drink for the session players, there is a certain pressure on the musicians to provide music of a listenable standard. A beginners' session to start off the evening might not be quite what the landlord had in mind. A back bar or upstairs room would be ideal, more like the sort of room you'd have for a song session.
