Ro-minimal / Micro House: Should you aim for "Mono compatibility" and does it still matter in 2021?

In this video I wanted to show you a little example of a Hi-hat track that was panned too far L/R in the stereo field.

The problem is, if switched to mono, it sounded very different than it was supposed to be in the first place.

In my opinion I don't want this to happen.

I want my tracks to be heard in the outside world like they were supposed to be heard.

Like they have been produced in my studio or in this case, the client's studio.
