It is normal that you can use the compat module for shadow.

It still uses some NIS functions for easier netgroup handling.

Yes, with initgroups_dyn() a initgroup call from login/su/cron is
much faster than without for some services. Because for some
services you don't need to parse the whole database, but you can
start a special query for the data you need.
Or for NIS: With initgroups_dyn, you can get all data with one
call, without initgroups_dyn you have to make one call for every
group entry, which is much slower.
