I couldn't agree more. I have a set of headphones that I love using with my phone and several computers. It's such an annoyance to connect it from one to the other and it doesn't appear that ANYONE is even working on making this better anymore. There was that brief period where some bluetooth devices included NFC where you could take it to the device to pair which was actually interesting but it only happened to such few products I have no idea if it ultimately ended up being usable or not.
It strikes me as a software problem in the device, not a bluetooth limitation.
For example, some devices that I have pair only to a single peer, while others have no problems switching between several, while another device is limited to two peers--requiring a reset if you want a third.
I suggest that anyone buying a bluetooth device test out pairing between multiple devices and if the device makes you jump through hopes to switch between bluetooth peers then immediately return it.
I found the NFC pairing feature to be pointless, tbh. The headphones still had to be put into pairing mode first, so the only step that it saved was going into settings on the phone and tapping the item in the list. It worked most of the time, but the one or two times that it didn't more than outweighed the benefits.
I bought an August EP650 Bluetooth headset recently that has NFC pairing. The problem is that my phone is the only other device I own that also supports it.
