It worked for me for the last 30 years.

We don't need to solve hypothetical problems, only those that happen
in practice.  In practice, only a small number of ALT combinations are
usurped by window managers, and they tend to be the same combinations
in all WMs, for good practical reasons.  We shouldn't expect that set
to grow or to usurp frequently used combinations, because that would
cause user outcry.
