Moo, if the manufacturers had used urea-formaldehyde in the first place, there would have been no need for you to have done all these re-gluing jobs. *G*

I cannot agree that ease of bridge removal is a factor to consider.

I have heard this line from repairmen before, but usually they are violin specialists who apply their violin thinking to guitars. Inappropriately in most cases.

I cannot visualise any normal situation in which it is necessary for a guitar bridge ever to be removed during the lifetime of a guitar, and presumably all the regluing jobs you have done were due to substandard gluing in the first place.
