Yes - but those kinds of change are generally for obscure corner cases or
long-obsolete features - and the problem generally affects only a
vanishingly small proportion of websites.

Here, we could easily affect close to 100% of WebGL programs - including
very recent ones - including those who followed the code in our example
programs and tutorials to the letter - and this is one of the newest web
API's, not some dusty old junk that people should have stopped using years
ago.

I think we have to tread very carefully.
