Hmm,  we had discussed the issue within R Core in a team meeting
many years ago.
At the time, those present agreed that we should emphasize
S3 (for "small" and "legacy" applications) and S4,
and concentrate on these rather than fostering even more
alternatives.

Everything else has been by contributed by R users who were not
happy with S4 ... at the time at least ...
Note that in the last several R releases,
 S3 <-> S4 "interoparability" has been greatly improved.
