Then let's describe it as a bug when newcomers run into these
predictable problems from the buggy behavior, and not as a feature
that helps the user handle dsp toggling the "right" way when doing

That's not my assumption. I'm not petitioning for changing Pd's dynamic patching
system-- I don't know the details about how it works internally. But virtually no one
uses [loadbangs] in the way described in the hypothetical examples used to rationalize
why it's desirable for the dynamic patching system to work the way it does. That should
be a good indicator that this imaginary library of abstractions which exists only in list
responses about dynamic patching should be removed and replaced with a simple
statement that "this inconsistent behavior is entrenched in Pd and cannot simply
be changed." (If that is indeed the case.)
