Also registered an account to bump the issue. Managing everyone's bags on a STR 8 sorcerer main character is a major nuisance. My party of 4 people practically stopped playing the game due to this and now I can only play alone or at times only with my brother. Changing the characters leads to major inventory management every time.
Why have multiple changeable companions, if the game penalizes us this severely?
Not to mention that this way everyone else's bags will always end up empty, so that I do not also get Encumbered every time I need to switch something. To me, this completely negates any logic behind the change.
If you are looking for more feedback, it seems a large number of people complain here:

One thing that stands out is this:
"Than [sic] the fix should be that they leave their bags when they leave permanantly."
