I think like with most large companies that still ship new stuff:
it gets a bit more complex for customers to figure out what the good nuggets are and what to ignore for now
same @ google, aws and so on
(I usually rely on opinions of people i trust to find the 'javascript — the good parts' version of large offerings)
the other extreme would be not to try and ship new stuff which is also risky
difficult to find a balance and probably a good idea to over-index on momentum and new stuff
while investing enough in hardening and improving the stuff that sticks
