I am building my new shiny WordPress plugin and since I've read about REST etc.I wanted to do things right and implement PUT and DELETE requests, and not just use POST and GET like I did until now.

But now I am wondering is it safe to use those. And by safe, I mean, are those requests supported by all servers in general or is general practice to have them disabled?

I don't want to implement everything now only to figure out later that just because of my wish to follow semantics my product is unusable for half of my customers.

Thank you
