Well, there is already a full feature replacement for gawk. It's called
GNU Awk. It is available in pkgsrc/lang/gawk.

Me too, but I would guess that in many cases, including especially the
"stupid" gawk command-line syntax, that's about as likely as getting the
GNU Awk developers to do the converse -- i.e. never.

None of those are in 'mawk' either, and the time functions can be
emulated with external commands using "system()|getline".

'mawk' also allows the RS variable to be an RE, and that might be an
extension bwk would take back for Awk, though he may have other reasons
for avoiding this enhancement....
That's about the single most important difference.....

Nope, not terribly different... :-)
