I don't know if I misunderstand you, but if with build tool you mean
your own solution, I don't see why you can't just as well add support
for `option handling' to your tool. I found compiling ffmpeg with my
desired dependencies tiresome, too, so my tool now is aware of .deps (and
.env) files I put into ~./script/options. The format is dep:VAR=VAL
(or simply dep) for .deps files, this will get picked up automatically
if I don't deactivate dependency handling. (In case of mpv, for example,
I override NUMJOBS via mpv.env to only contain an integer, no -j option,
otherwise it complains.)

The upside is that I can save these files and use them on other machines
easily, and no additional field in .info files is needed.

If I recall correctly, slackrepo also has (more powerful) so-called
hintfiles, and Karel Venken's `getpkgs' also has support for a HINTS
file, but I have little experience with these tools.

No offense, but I think people compiling SlackBuilds by hand know that
it won't be convenient, and those who use (their own) tools have the
ability to specify additional dependencies via their build tool, at
least theoretically. As long as additional dependencies are listed in
README, I see no reason for any big changes in the way we handle
SlackBuilds from SlackBuilds.org.
