I don't believe there should be a way to cross the lava oceans easily be it strider or boat.
I've never been in favor of any vessel be it obsidian/netherite or wood from the stems of the assorted wood fungi. It shouldn't be easy, that's the whole point, yet there is a percentage of players who want everything handed to them easily on a plate instead of face a challenge. So no I don't believe there should have been any kind of boat let alone a strider, which I feel is a step in the wrong direction. Get the piglins to trade with you sure, but then make it even easier by having gold ore in the nether too.
I have to question the direction some things are taking, the new biomes in the nether for me are most welcome despite being one who has thought the nether didn't need "Doing up" but striders are IMO, a step too far.
