It doesn't seem like a problem to me. What did you have in mind?

This isn't some constant that we might change. It's more like writing

 (define FIVE 5)

except that it's so difficult to write the `quote' symbol in C that we
really end up writing the equivalent of

 (define QUOTE 'quote)

sometimes.

A `scheme_quote_symbol' could be defined somewhere and exported to the
other places. The tradeoff is writing `(define QUOTE 'quote)' multiple
times versus making a global change.
