This really is a very simple point, but perhaps a simple analogy will
help to clarify it. You don't throw out your 3/4" just because you've
bought a 19mm. There is room for both in the toolbox, and why write 3/4"
on your new spanner? It /isn't/ a 3/4" spanner even though it's very
like it, so why pretend otherwise?

You have a good 3/4" spanner.  You don't throw it out just because you
also get an adjustable spanner - sometimes the 3/4" spanner is more
practical, or perhaps a bit stronger.  That's keeping C when you also
have C++ available.

You have a good 3/4" spanner. You also have an adjustable wrench.

They are welded together and and the 3/4" spanner is written
in the language of the adjustable one ...
