<shrug>, this has been an often requested tasksel feature for years, and
was finally implemented. Tasksel does not have a database of installed
tasks, it works out what tasks are installed by examination of what
packages are installed.

No, that is not how tasksel's task removal support works. Tasksel will
only remove a task if it was marked as installed when tasksel started and
you took an explicit action to un-select it.

It seems more likely to me that you ran into some dependency issues in
installing the file-server task, or had some other problem with your
system, and aptitude decided to resolve the problems by removing
packages. Without a transcript, I can't say for sure. You might check

Anyway, this has nothing to do with the original bug report.
