Not sure I understood - waiting for your patch...

To be honest, I'm not sure I have ever clearly understood that ";binary"
issue, and I don't have time to dig out the documentation, learn about
it, and check the code, since the whole stuff seems to be obsolete.

None that I know of.

I think compatibility with obsolete stuff is something that may easily
get in conflict with open source, volunteer developed software.
Volunteers tend to concentrate scarce resources on important things, and
preserving compatibility with obsolete (often broken) stuff is first of
all a waste of scarce resources, and second, but not least, reduces
pressure on obsolete (broken) software makers, which typically are not
volunteers but actually get paid for (obsolete/broken stuff). Having
said this, you may find volunteers that, pushed by their own needs like
to spend time supporting obsolete/broken stuff for the simple reason
they need it.

No. This question has been raised many times, and the answer has always
been like that. All you could do is hack slap_send_search_entry() in
