Thank you. I've seen 'only-on-Vercel features' mentioned in the past, but so far, I have yet to find any specific examples of classic 'vendor-lock' in a sense 'if you use this it will not work anywhere except for Vercel'. AFAIK you can self-host NextJS apps with docker, albeit some features may not be as efficient as on Vercel they will work. This seems to be the case for both of the examples mentioned—ISR [1] and image optimization can be done on CloudFlare for example. Am I missing something? Don't get me wrong I'm not affiliated with Vercel, I'd like to think we can still switch from Vercel-hosted NextJS to self-hosted Docker in the future if we want which was my impression so far.
