This dependency is still in place for nvidia-kernel-support
510.60.02-1 from experimental.

yes, and there is nothing wrong with it

Previously (510.54-1) there was a nvidia-modprobe package. But it is
no longer generated for 510.60.02-1, effectively it doesn't exist any
more.

Where do you get that impression from? src:nvidia-modprobe has been a separate source package for ages and there are no dependencies requiring the version to be in sync with the driver (beyond the major version requirement in nvidia-kernel-support).

We can workaround it for now by using nvidia-modprobe 510.54-1 from
unstable, but will that introduce errors with 510.60.02?  And that

Guess why there is 'only' a dependency on (>= 510) in nvidia-kernel-support. (Even that is more tight than usually needed, but it's automatic and I forgot manual bumping (if actually needed) often enough.) So far, all old legacy and tesla release series work with the latest nvidia-modprobe version.

will become a serious bug anyway once 510.60.02? is uploaded to
unstable and nvidia-modprobe is no longer available at all.

Does the nvidia-modprobe package need to be generated for 510.60.02-1,

no, usually only upstream releases that bump the major version bring relevant code changes, while minor version bumps usually only update the version number (in multiple places)

or does nvidia-kernel-support need to be updated to stop depending on
it?

no

PS: src:nvidia-graphics-drivers-tesla-510/sid currently requires nvidia-modprobe/experimental to be installable (and therefore does not migrate to testing), but that wasn't the package of your concern

PPS: currently sid is the staging area for getting the driver stack updated from 460 to 470 in bullseye, newer releases will enter sid after that has been sorted out
