Yes, yes, yes!

Ours run on Solaris.

Sometimes (but, not, IIRC, always) I can delete the data set
from the NFS client side.  But sometimes the ENQ comes right
back when I re-create it.

I've deferred reporting this because all the data sets I use in
this fashion are expendable.  I can just choose a different data
set name and proceed.  Problem finally clears up at NFS recycle
or IPL (the server is a lab system, IPLed weekly), but it has
persisted longer than any plausible time out value.  If I could
re-create the problem at will, I'd report it.
