No, Creates friction.
Before: user could just copy and paste whatever he saw into the browser
Now: copy and paste, find out that it doesn't work, find out why, find out he needs a conversor, spend time to find a conversor, download a conversor, install it, run it, paste, find out it doesn't work..
And once they know why (because e,p etc is missing), add it
People just won't do that
