Why does LR not support opening multiple catalogs simultaneously like you can do in Premiere?

Having seen multiple catalogs in relation to LrC discussed many times, and the consensus I think I've seen that you only need one in a majority of cases, I'm curious if your use of 50 catalogues is driven by features thar Premiere does not have in relation to LrC Library features. Curious what drove you to having so many catalogues.

I think the specific reason you are asking for is that this is not a design feature of Lightroom Classic. Sure, Adobe could do it but its not on their list of things to do. Using software in a way that is different to the way it was designed to work best is usually an exercise in frustration.

Comparing Lightroom Classic and Adobe Premiere is comparing apples and oranges. These are totally different applications. About the only thing they have in common is that they are both Adobe software, but apart from that, why would 'Premiere can do this' be an argument that Lightroom Classic should be able to do it too?

P.S. the fact that you opened 50 catalogs is the best possible argument for using one single catalog rather than multiple catalogs. That is how Lightroom Classic was designed.
