Yes, that is a good point.  I have considered $<$ and $>$ which have the
advantage of more readably indicating "bracketed-ness", but those
symbols should perhaps be saved for something else.  Maybe:
$<sqb$ and $>sqb$.

That seems reasonable.  I think we might want to allow
hyphens and underscores; haven't checked their categories,

They're supported (and implemented in Kawa) for both SRFI-108
and SRFI-109.   Not yet for SRFI-107, though I plan to add them
