I think OpenGL is important as a simple, "universal" legacy standard. As long as it's supported (with reasonable performance), through something like Zink it's fine.
As someone who is new to graphics programming, the pervasiveness of OpenGLES3/WebGL2 is really great. It's a single relatively-simple standard that is almost everywhere.
Desktop OpenGL isn't simple, it's hard to use and even harder to debug, and it doesn't have reasonable performance unless you know which APIs are mysteriously slow.
WebGL is covering up a lot of stuff for you, but it's better to find/create a modern "simple" API on top of a modern rendering API if you want one.
