Sure, but all the same it would be weird for a user who does not know 
that LMT means "approximate placeholder" to see a transition like this:

Zone	Europe/Paris	0:15:00 -	LMT	1891 Mar 15  0:01
			0:09:21	-	PMT	1911 Mar 11  0:01

for France's institution of a standard time zone in 1891.  That would 
appear to be a transition from a GMT-based time zone to a 
let's-thumb-our-nose-at-the-British time zone, which is not at all what 
happened.  In contrast, the (non)-transition that's currently in the 
database feels closer to what actually happened.

Yes, this is subjective, but the proposed change feels considerably more 
artificial and forced than what we've got.
