Why do you think they're more likely to serve your audience with <canvas>?

(It's generally a bad strategy to try to hack around bugs or holes in
the platform by proposing new functionality - new functionality
generally takes longer than bugfixing, and the new tech may have the
same bugs or holes (or even more likely, exciting new ones!).)

Incorrect.  A million developers doing a million different things will
mostly do things wrong when the correct solution requires extra effort
and doesn't have immediate visual or functional feedback telling you
if it's working or broken.
