Objectively those two are present in F$EDIT and missing in DBASIC$EDIT.

Why and whether that is a problem or not does not change the
reality.

Documentation does not say.

I suspect DCL only.

And a little test does not invalid that:

$ write sys$output f$edit("xx ! yy", "UNCOMMENT")
xx
$ write sys$output f$edit("xx # yy", "UNCOMMENT")
xx # yy
$ write sys$output f$edit("xx ' yy", "UNCOMMENT")
xx ' yy
$ write sys$output f$edit("xx // yy", "UNCOMMENT")
xx // yy
$ write sys$output f$edit("xx /* yy */", "UNCOMMENT")
xx /* yy */
$ write sys$output f$edit("xx (* yy *)", "UNCOMMENT")
xx (* yy *)
