I’m clearly in the minority here but, I pulled my antiquated, non functional A/C off my 930 17 years ago. Compressor, condenser, brackets, hoses etc. Like all the other parts pulled for weight savings, it was all moth balled.
911s are not the best balanced sports cars. 60# is a hell of allot of weight in the worst place on the car. To say it’s insignificant or not noticeable is completely contradictory to my experience.
So is being as slow as Honda Civic

Along with all the A/C components I also pulled the factory air box (mailbox), switched to a long neck innercooler, aftermarket turbo, headers and exhaust and a few others. Obviously, allot of my mods gave me HP gains but the weight savings is a huge part of the overall performance gains. The factory exhaust is also really heavy.
By the time I finished my mods my car went from Euro ride height to literally safari ride height.
Something else, I think that’s worth mention is the transformation of the engine bay. Removing and or replacing all of these components was a game changer when it came to engine work and maintenance.
Also, let’s be honest, those old compressors are fugly.
And TBF, I live in Seattle. So here’s that. There are days where A/C would be nice but I just don’t have that kind of disposable income. If I did I’d definitely go electric A/C
