"missing" SAs/ENs?

We just had a big dump of multiple SAs and ENs yesterday.  At least one 
of those I know has been pending for months (and AFAIK was ready to go 
technically within days).  Additionally I know of and personally have 
been hit by 3 other things that I feel really should have been ENs and 
out by now (and am maintaining my own patches for):

1. loader handling of root geli disks is broken.

     This one is a big deal, it completely bricks systems, there has 
been a patch for months.

2. userboot.so doesn't work when compiled with BIND_NOW. relatively 
minor, affects few people with non-standard build options, but likewise 
known for a long time, patch committed.

3. compile hang in certain circumstances with LLVM with CPU targeting on 
AVX512 processors.  Again, minor, affects few people with non-standard 
build options, but also know for a long time with a patch


I suspect by the fact that I've personally hit these 3 that there exist 
many others that other people have hit that I have not (yet.


It feels like there is a backup or stoppage of EN/SA processing.
