Any news on this? If it's just one constant whose value I would have
to increase in my private copy of the code, before recompling, for
testing purposes, which one would that be?
Unfortunately, it's not just a single constant; there are a number of
hardcoded values that all need to be changed in a consistent way.
I'll try to get an experimental patch ready shortly. Or, of course,
someone else is welcome to try. I don't think it's very hard, but it is
more than just a single number.

There could be some subtle problems that simply changing the character

In particular, the allocation size of a "whatsit" language node might
also need changing, which would require adjusting other code in the core

a "whatsit".
Or not. I can't tell from the TeX source what the bit sizes of these
node fields are. But if they're too small to fit a pair of enhanced
character count limits for hyphenation, there will likely be bugs elsewhere
due to truncation or wraparound in the arithmetic.
FWIW,

AFAICS, this would only become an issue if we allow \lefthyphenmin and
\righthyphenmin to be given larger values; currently, they're limited to the
range 0..63 (actually, it's possible to set the parameters to larger values,
but they'll be clamped when stored in a language node).
But I don't think that's needed here; surely there's no realistic use-case
that requires setting the *-min values greater than 63, even when
hyphenating 1000-letter Sanskrit words.
The contrary is true. These long strings are not single words, several words
are glued together. For instance, Bhagavdgita contains श्रीभगवानुवाच which
are in fact three words श्री भगवान् उवाच. It makes no sense to increase
values of \lefthyphenmin and \righthyphenmin.
