Hi

Technical difficulties  associated with keep lvmetad in up-to-date state have 
been  high - and the replacement, which uses the the structures/files in 
/run/lvm directory in form of hints is more easier to maintain and we are able 
to achieve similar functionality as with running daemon.  It's worth to be 
noted that lvm2 is now using significantly faster scanning mechanism - so the 
usage of lvmetad in same cases has been actually slow-downing the system....

See the man page   'man lvmautoactivation'  for more detailed description 
(although the page needs some updating as we have improved recently some pieces).
