Thanks for your feedback! So the current plan is to remove the support from
current upstream kernel in ~3 years, as people noted, you can still use
upstream -stable kernels branched at the end of the deprecation period for
another two years which gives you around 5 years to migrate if you are
using upstream stable kernels. 

You can still use sufficiently old kernel (VM?) or FUSE (although someone
motivated would probably need to write proper support module but e.g. grub2
has reiserfs support in userspace implemented) to get data out of
Reiserfs partitions after that... At least that's the current plan.
