Comment 22 for bug 1892435

We customized our eg2 splash page to be the same as our eg splash page with no problems, but we don't make changes to it very often - usually just at upgrade time.

But if you do need to make frequent changes, I can't think of any reason why you wouldn't be able to do that. The code for that page (\src\eg2\src\app\staff\splash.component.html) is mostly HTML, so it's just as easy to update . The only difference is that your vendor would need to run ng build to get your changes to appear. I expect they could even set up a script to run ng build nightly, or on the same night every week if you do weekly changes.
