So there will be some effect of this reordering, if some
clear-message-function does something that you say it shouldn't.

This whole discussion started from a request to be able to accumulate
messages in the echo-area so that the user who is away could see them
all when he/she comes back from whatever took him/her away. There
could be quite a lot of messages accumulated during that period, and
the request was to leave them all on display. For which you proposed
to use clear-message-function in a way that doesn't actually clear
them.
Is the above an accurate description and summary of what is being
proposed here? If so, is it now clear what kind of job I think
display of echo-area messages was never designed to support?
