Absolutely! that's why I build IE11-compatible marketing pages and signup... once they are past the first step of the funnel, the back button isn't as tempting :) Right now its the same front end stack (Vue, BS4) for both sites, and re-build and re-test for IE11 infrequently, so we're not paying the cost constantly.
