The time for such radical changes was during the very early development
stages of Unicode. Now, even minor alignments of such properties can
cause major dislocations: it's not a matter of search and replace,
because that assumes the reader views a document in an editing context
and is willing (and able) to actually modify it. It affects web pages
and lots of other, non-editable contents.
One of the key lessons of Unicode is that, while software may get
patched (in certain situations), *data* is permanent, which requires
reanalysis.

That's an implementation bug - as long as mirroring is consistently
applied between authoring environment and the time you are viewing the
text, then you should not be able to notice it, even. It should just work.
