Couldn't this be obviated by there being a read-only substrate, embedded
within which are editable regions corresponding to SRC1 and SRC2?  I.e.,
SRC1 and SRC2 are separated by a region of text that cannot be modified.

Org mode has a somewhat "working" solution.  While it's not free of
corner cases, it's not clear that it would be impossible to resolve said
cases.

See above.

Out of curiosity, is the difficulty in "other similar issues" inherent
to the concept of having a "meta" buffer within which exist multiple
regions each corresponding to a distinct buffer, or does it have more to
do with the technical details of the current implementation?

>From my perspective, the value of a single such "meta" buffer is purely
in the UI.  Specifically, for me the value isn't potential performance
improvements while editing, but rather the potential improvement in
usability when performing, say, somewhat complex refactoring across a
code base.  I.e., it is entirely okay if in the background there are
distinct buffers that remain open where modifications occur, as long as
the changes are reflected into the "meta" buffer.
