Should not change the values in my metatag fields unless I want it to

Yoast by default will replace the tokens in my metatag fields with text when I save a node, effectively hardcoding this text into the database in the metatag table. So if I later change the title of the node or the summary my metatags won't update.

I get the idea that you should always write specialized metadata, but on my own website and on my clients websites there is a lot of "trash" content we don't care about and there is some key content. For all the trash content just using tokens is adequate in my opinion, and I would prefer if Yoast didn't mess with that setup. :p

Yoast could detect if I used tokens in my metatag fields, or it could detect if I had ever manually edited the snippet for this particular node. Or even easier and probably more robust there could be a simple checkbox which said something like "Have Yoast take control over your metatag fields" which could be unchecked by default.

I haven't investigated this issue at all yet because I just installed this module, but the last option is what I'll try out first.
