cambria is the benchmark ... indeed bonum looks somewhat weird (also
because the f is rather tightly bounded; the same with pagella)
(there are some primes-*.tex test files in the test suite)
the primes mechanism is somewhat non-trivial as ' is not really the
prime symbol and some additional parsing / hackery happens; also,
traditionally primes in tex sit on the baseline and need to be lifted
one problem is that texgyre math is still beta so messing around at the
tex end will interfere with improvements
