I think the only reason was that these characters already had been
escaped in `org-link-escape-chars'.

The commit removed the special rules for the letters with
diacritics. The previous commit (0c4bb0e) introduced an algorithm that
covered non-ASCII characters in general, thus special rules for
letters with diacritics where no longer necessary.

I can only speculate why they were escaped in the first place: + ; and
= do have special meaning in HTTP URIs and IIRC Org did not draw a
strict distinction between escaping for internal purposes and escaping
of HTTP URIs.
