No, it won't block messages.

It will display messages together with the minibuffer contents
instead of replacing it.

Currently it requires the user to wait 2 seconds
before the user can see the minibuffer contents again.
Most often, this happens after typing M-n to see if any default values
are available, and it replaces the minibuffer contents with the message
“End of history; no default available”.  I have to wait several times
per day for this message to go away.  Totally it takes ~1 minute per day,
~300 minutes (5 hours) per year, and ~50 hours per decade - this is
a whole workweek of just looking at the message and waiting for Godot.
