OK, let's go a step further - what if syslog dies or breaks in some way
shape or form so that the syslog() function blocks...?

My worry is the one that was originally raised but ignored: syslog() should
not BLOCK regardless of whether it's local or remote. syslog is not a
reliable mechanism and many programs have been written assuming they can
fire off syslog() calls without worry.
