I have no opinion on whether we want these particular Assert() calls,
but I note that using Assert() in front-end code only became possible
in February of 2013, as a result of commit
e1d25de35a2b1f809e8f8d7b182ce0af004f3ec9.  So the lack of assertions
there may not be so much because people thought it was a bad idea as
that it didn't use to work.  Generally, I favor the use of Assert() in
front-end code in the same scenarios in which we use it in back-end
code: for checks that shouldn't burden production builds but are
useful during development.
