The change is described at
under "4.6 Apostrophe Semantics Errata", as one of "corrigenda" that
"clarify the semantics of different apostrophes". In reality, it was a
semantic change, as you describe.
I think we can read the rationale as being implicit in the explanation.
U+02BC MODIFIER LETTER APOSTROPHE is a _letter_ (even by its formal
category), so it wasn't quite logical, and it wasn't quite practical (for
lexical scanning, for example) to recommend using it to represent what we
commonly regard as (punctuation) apostrophe.

Many people have expressed the same view. It would meant that a new
character would have been defined, for unambiguous use as punctuation
apostrophe. I don't think traditional or modern typography ever
distinguises between a punctuation apostrophe and a right single quotation
mark (even though such distinction might be useful in some situations, in
texts containing both of them close to each other). Thus, the difference
would be _purely_ semantic. Would people really want to make such
distinctions in writing?
Similarly, the use of the full stop character "." as a sentence
termination (period) is semantically quite distinct from its use in
abbreviations (as in "Mr."), and its use as a decimal separator (in
English) or as a thousands separator (in many other languages) are
semantically distinct, too. Making distinctions on purely semantic
grounds, for a character that is commonly understood as one character with
multiple uses, would apparently have opened a can of worms.
