Um, where are you even getting this idea that LVM2 is in maintenance
mode?  Or that snapshots haven't improved?

Sorry to come off defensive but your entire post is founded on incorrect

Anyway, if you look at the change history of the lvm2 repository (be it
cvs or git, cvs commits are mirrored to git) you'll see there have been
regular changes flowing in and most recently a very extensive evolution
of the code to add support for thin provisioning with highly efficient
snapshots (ala btrfs or ZFS).

try: git clone git://sources.redhat.com/git/lvm2

Please, could you tell me if is there a gitweb interface somewhere?
