Your wording seems to (unintentionally, I'm sure) slightly misquote 
prior statements.

Geert is suggesting the deletion of the Perl variant (which means you 
have had no choice when you had problems with the C variant).

I am, _on the other hand_, suggesting adding documentation (leaving 
the option to at least try the Perl alternative when the other one 
doesn't fit user's needs or fails for whichever reason). FWIW, I am 
against deleting the Perl variant.

FWIW (not that my opinion has any special value), I would agree to 
its deletion if the C variant would serve users in each and every 
single case. Your example shows this is not the case.

Let me put it this way: IMHO, the possibility that the Perl variant 
might not achieve its goal in certain cases is not reason enough to 
delete it. Remember that the C variant included in Syslinux has 
limitations too.

The known issues should be an encouragement to improve them, both.
