There is also the question of searching a document, either in a reader
or using google.

Often the same users who want to make pdf's from source files they wrote years
ago are upset when searches fail.

There have been massive changes elsewhere (unicode fonts, wide characters, etc)
to improve support for languages other than Western European.  People
need to be
able to create documents with passages, proper names, etc. in many languages.
When preserving compatibility makes it harder or even just different for users
outside the western hemisphere, there is nothing that will please everyone, so
a hard choice must be make and it is not a given that compatibility should win,
or even that spending time, effort, and space on compatibility should take
resources away from efforts to make TeX more useful for a wider audience.
