Hi Peter,
I’d like to give you some arguments/info about your concern.
As you said, you still using Photoshop CS6 (which is a 8-year-old software) because this is what suits you the best (perpetual license as well as, I guess, all the features you need for your workflow).
This decision needs you to be ‘careful’ about how you upgrade your machine. Any new updates, especially the OS, could break your workflows anytime, because of this choice (to stay with PS CS6). At the same time, the IT world doesn’t stand still, and a lot of things have changed since 2012. Eight years in this field is a geological age. At DxO, with PL, we guarantee to our customers that our latest version is compatible with older OS (the last tree OS for the mac environment).
When you provide compatibility with an older OS, this implies that any bug and or problem found on those older OS have to be fixed. This means that for each version of PL we have to extensively test it in 3 different environment. Having said that, this is not merely a “test & fix” problem: new OS offer new possibilities, new API, better performances and so on.
In the digital/IT world, continuous improvement is a simple reality.
You are absolutely free and can decide to ‘jump off the train’ and stop wherever you feel the most comfortable, but you can’t blame us because we move forward.

Let me know if you need any further help/info.
Cheers,
