Install e/OS on Fairphone 6

Alright, that makes sense.

In that case, would it make sense to install this version (e-3.0.4), and then update later to be able to lock the bootloader? I am not particularly interested in spending efforts setting things up on Google Android if I know I am going to be leaving soonish.

But I am wondering if updating from 3.0.4 to 3.1.1 or whatever the next release with newer SPL is, will in fact need me again to use bootloader and therefore erase all data of the phone? It seems to not be the case looking around for info on updates
