Isaih, this is good news: you can't insist on removing stuff, but if you
put the cleanups and better organization in new clothes, the old drab
ones will fade into disuse (even if they don't ever go away).
This is kind of a "law of the Web." It turns out compat does break, and
no one notices (much), over very long timeframes. At least, we saw this
going from the early Web to the modern days, with a few things (corner
cases in JS and CSS table layout). But these were never predictable, or
With strict-by-default modules, we can hope for 'with' to whither away
over a decade. I wouldn't bet on it, since strict mode is still opt-in
and will be for <script>, forever.
