xyz:servers vs. xyz:subdomains #1

Hi. I'm wondering if xyz:servers might be a little more intuitive to people who use LeafletJS if it was called xyz:subdomains. I'm not sure about the nomenclature for other libraries.

OpenLayers does it completely differently, there it is {?-?} (e.g. {a-f}) so you need to do some preprocessing anyway to pass it over.
If I understand the MapBox docs correctly, there you can actually define different URLs via an array, so in principle you could provide https://{s}/maps/{z}/{x}/{y} and then set xyz:servers example.org and mirror.cloud.

That's the intention behind it. Thoughts, @DanielJDufour ?

Ah okay. That makes a lot more sense. Hmmm... it's sorta tricky because it seems Mapbox and LeafletJS usage of {s} is in conflict. I'm not sure what to think, but I'll give it some thought.

What we'll do with {s} is that it's just expanded into multiple URLs.

If you have https://{s}/example and xyz:servers is ["a.com", "b.eu"] you'll expand that to ["https://a.com/example", "https://b.eu/example"]
