Resin is shipped dry and can be stored dry.
On-The-Go mfg. even recommends draining softener if not going to be used for extended periods.
Won't hurt the resin.
Must depend on the manufacturer.

Resin beads that have dried out become free flowing and some shrinking of the beads is evident. Dry beads will re-swell
very rapidly when placed in aqueous or other polar solutions thus causing severe strains, which may lead to bead breakage.
Should the beads become dry, they may be hydrated with a saturated sodium chloride solution. The salt is removed by
successive dilutions and decantations. It should be emphasized that this re-hydration method will not result in complete
elimination of the bead breakage; therefore, it is important that the resin is not allowed to become dry, except for desiccant
applications.

Dehydration - One of the major risks is that resins dry out. Unless rewetting is carried out carefully, beads can crack or break on rewetting.
Draining the softener does not mean 'drying' the softener.
