It's just serverless architecture. It may not fit for every project.

We use the concept to add meta tags to our client-side-rendered webapp for search indexing. We can decouple our client app from our server and deploy each separately. We use "serverless functions" to add some meta tags that need to be added server-side.

I mean, it's incredibly easy to deploy client apps separately from the server in a lot of ways

To me, the only value I see for Edge compute is when some chunk of data requires processing going one way across the network, and that processing can be done entirely locally. I suppose what you describe with the meta tag qualifies in this case, otherwise I think serverless architecture looks like a pretty sweet deal for the cloud companies promoting it.
