You're right, and furthermore we now have `phw`, a facility lacking in 2020,
to more directly inquire about such things.


$ cat EXPERIMENTS/66803-hw-and-environment.groff 
.ll 1p
1. facilitate
.tm user-defined hyphenation of "facilitate" in environment \n[.ev]:
.phw
.hw fac-ilit-ate
.tm user-defined hyphenation of "facilitate" in environment \n[.ev]:
.phw
2. facilitate
.ev new
.tm user-defined hyphenation of "facilitate" in environment \n[.ev]:

.ll 1p
3. facilitate
.pl \n[nl]u
$ ./build/test-groff -Wbreak -z EXPERIMENTS/66803-hw-and-environment.groff
2>&1 | grep fac
user-defined hyphenation of "facilitate" in environment 0:
user-defined hyphenation of "facilitate" in environment 0:

user-defined hyphenation of "facilitate" in environment new:
fac-ilit-ate

Hmm, yeah, your (correct) observation perceives additional chaos regarding
whether hyphenation parameters are global or environmental.
