Would it be terrible to make attempts to mutate the 'is' attribute

not mutable?
We already have several attributes that are immutable but don't throw or
anything when they're changed.
e.g. <script src>, <html manifest>.
In the case of manifest, we omitted the IDL attribute to signal that it
shouldn't be changed.
As another example, <input type> was immutable in old IE and that made
people think of it as immutable.
