integration-heavy problems are extremely painful, and they are moving targets over which you have very little control.

if your business depends on universal integrations in order to welcome customers from diverse ecosystems, you have a choice: you can couple your apis to N moving targets and maintain that risk surface forever, or you can delegate it to someone like merge. (i think, i'm not a merge customer, but i've dealt with that problem inside businesses before and would have been interested on that basis).
