We had a similar discussion for ‘cc’ vs. ‘gcc’, but in practice ‘cc’ has been rare enough that it’s not worth bothering. I believe Autoconf-based packages do not have any problems with ‘flex’ and ‘bison’. What package was it? How hard is it to work around? We should at least be consistent. In guix we have a (hard) link from sh -> bash For consistency I believe we should also have csh -> tcsh lex -> flex yacc -> bison cc -> gcc egrep -> grep Then there are various versioned commands: python3 -> python wish8.6 -> wish Otherwise, individual packages are forced to do substitutes - not particularly onerous, but it makes the maintenance a pain.
