One disadvantage of diversity is increased maintenance costs.  Three
sets of bridging code are going to need roughly three times as much
maintenance effort as one set.  This is an ongoing cost that is borne
by the Project as a whole.

Even it the code comes with an iron-clad promise that the initial
committer will continue to maintain it, circumstances change and
that person won't be able to maintain the code for ever.

I don't know enough about the pros and cons to make an informed
decision in this particular case, but there need to be definite
benefits to justify the increased ongoing effort.
