No! No! No! Your enthusiasm is in all honour. But this is not correct, because the /e/asy installer has been installing /e/ OS ‘stable’ Oreo-8 for months, but not Android 1Q ‘stable’ at all.
On 05/04/2021, I have the same eight ‘O’reo files with the/e/asy installer version v.012.2-beta as I have today with version v.012.3-beta. It is definitely /e/OS 'O’reo 'stable’.
If @ccgauvin94 is content to change his stock Android 8.1 for /e/ OS 'O’reo-8, the /e/asy installer can be an installation aid. However, if @ccgauvin94 wants to use /e/ OS ‘Q’ Android 10, then he must first install stock Android 10 and then install the dev version, because /e/ OS ‘Q’ ‘stable’ is still not available at this moment.
If an attempt is made to change OS on an S9 ‘starlte’ with Stock Android 10 using /e/asy installer v.012.e-beta, the S9 SM-G960F becomes inoperable. There are enough frustrated us/e/r since late January 2021 (release of e-0.13-q-2021 0120 97133-dev-starlte).
