The --hold feature was introduced with snapd v2.58 which was released as recently as Dec 1, so less than 9 months ago. So I would consider this a relatively new feature.

Furthermore, as best as I can tell from the documentation, there isn’t even a way to configurably hold updates in general or for a specific package like can be done with apt-preferences; refresh.hold only allows 90 days out.

I think it is a perfectly valid criticism that the snap developers didn’t implement this feature at all until well into the life of the product and then, even then, done begrudgingly at best evidenced by the minimal implementation.

Now, I feel like I did my research, but feel free to let me know if there’s something I can do better or if you have any other general life advice for me.
