Martin,
The old data set will certainly stay for a while (or indeed indefinitely, why
not). To make the transition as smooth as possible (I am aware that "maps" is
used in more places than I can ever check myself) I am including the
possibility of switching back to "legacy" mode using an environment variable
(or an extra function "world.legacy(TRUE)"), so that any code that runs into
trouble can be switched to the old database without needing to edit the code
itself.
Would it be a good idea to make the new maps package (beta) available (e.g. via
github) prior to submitting to CRAN? It is more or less ready. Given the many
packages that call maps, this could give maintainers a chance to check things.
For the moment, it's only the country borders & names that have changed.

I agree ... but the following is not about 'maps' in particular,
but package maintenance / compatibility ....

I know these data sets are not very small, but I would still
strongly recommend that you
keep the old map, say as "world198x" (and change the "x" to a
digit if you know which one, or the "8x" to "7y" ... etc).
Storage and bandwidth have become considerably cheaper and so
the package could provide (almost) back compatibility ... and
also something interesting in itself (comparison of two very
similar maps with R; teaching, history, ...).
Best regards,
Martin
