Is it worth upgrading to 16.22 if you are still on 15.77?

Hi, 

I've switched off automatic upgrade in my watch and when new firmware become from beta i'm waiting for service pack.  and i see now that are many claims on 16.22.

on my Fenix 7pro ss i have battery drain and want to have lap undo as feature. all others looks ok for me.

1. Is it worst to upgrade for 16.22 now? 

2. how Garmin usually do? can i expect "service pack" which might fix current bugs on 16.22 to be released soon? like new update of current 16.22 with fixes.
