Arbitrary length?  Surely they won't be tens or hundreds of bytes
long?  But... even if this were so, surely the codes that come after
the initial escapes (one or two or three) will all be in the printable
ascii range (0x21 - 0x7e), right?  So verbatim input could just insert
the initial 0x1b bytes and leave the rest as if they were normal
characters getting typed?

That will work with the above method.

Okay.

Bracketed paste mode...  That would have to work entirely differently;
it would have to treat reading from the input as if inserting from a file.
Currently, when you paste something with the mouse, each character is made
room for, inserted, and the undo item is updated.  Lots of overhead.  And
when undoing the paste, each line is undone separately.  The entire paste
should be undone as a whole, like an inserted file...

Anyway, entirely different matter.  :)
