I don't think you understand what my comcern is. It may be that it isn't
a big enough risk that its worth worrying about. But I'll try to describe
it better.

The user has some files in is home directory label say special_t that are
not writeable by processes except for a few given processes. There are
some processes which read these files (but not ones labelled user_home_t)
and do things where one would be concerned if bad data was in these files.
These files' names are known to selinux for relabelling purposes.

Some app is run by the user. This app then removes files labelled special_t
and creates new ones with the same names labelled user_home_t as normal.
The daemon process then relabels these files to special_t and bad things
proceed to happen.
