Recommending the use of reiserfs is wrong. The Debian installer's
development version's kernel no longer supports reiserfs (see [1]) so
it's safe to assume that reiserfs support'll be dropped from Debian at
some point. You'd have to ask the Debian kernel maintainers whether
it'll be dropped in Debian 8 or 9.
[1] From the "linux (3.10.1-1)" changelog:
* udeb: Remove obsolete and unsupported drivers and filesystems
- Remove ppa from scsi-modules
- Remove floppy-modules, irda-modules, parport-modules, plip-modules,
qnx4-modules, reiserfs-modules, ufs-modules
