This is so you can just refer to - here - aspell and it will
lead you to a specific version, or just the version that is
currently installed.

It has to do with versions as well:

  The symbol versioning is a GNU extension to library
  versioning [that] allows a single externally-versioned
  library (e.g. to provide multiple incompatible
  implementations of the same symbol (before symbol
  versioning, you had to update the external version of the
  library every time you introduced incompatible interface;
  but with symbol versioning you don't). [1]

I have tagging with my e-mail, you can send a mail to even ...

Not sure what tagging you refer to tho? Maybe symbolic (or
soft) links are pretty useless, is the disappointing truth?
