This is a reasonable position, but rna is a special case.
We could make life easier for our users
by eliminating stumbling blocks like irrelevant inconsistencies
between leaprc files. For example, I tried to diff dna rna leaprc pairs
in anticipation of using the patch command to convert a dna leaprc
file into an rna one, but this was not as simple as it should have been.
