> I question this. Each vendor's offering has its own peculiar prompt quirks, does it not? Theoretically, switching RDBMS vendors (say oracle to postgres) was also "an afernoon's work" but it never happened. The minutia is sticky with these sort of almost-but-not 'universal' interfaces.

The bigger problem is that there was never a way to move data between oracle->postgres in pure data form (i.e. point pgsql at your oracle folder and it "just works"). Migration is always a pain, and thus there is a substantial degree of stickiness, due to the cost of moving databases both in terms of risk and effort.

In contrast, vendors [1] are literally offering third party LLMS (such as claude) in addition to their own and offering one-click switching. This means users can try and if they desire switch with little friction.
