Maybe Alexander had reasons to add "--without-profiler" without any
configuration option. He added three more options within the same patch
but left only this one fixed to "without".
So the compromise could be to add a new configuration option with
default value of "n" and add this configuration option as a dependency
to python3-lxml?
But as long as we don't know Alexander's reasons to do so, compiling
with the profiler option could break something else.
