I personally don’t have any problem to change the partition if i would reinstall my system.
I wrote this only for one reason, because i had the unexperienced Windows to Linux switcher in mind… who maybe press auto install.
Yeah im aware there are some Pro’s but there are many con’s also or maybe did that changed in the last 12 month’s. You may remember a few topics where we was talking about the Pro’s and the Con’s from BTRFS?
Maybe i miss something? I remember slightly where you disagreed with me that BTRFS is not the standard for a Manjaro install (i had mistaken the install procedure with nobara distro at this time) but where you agreed with me that BTRFS shouldn’t be default install for Manjaro… maybe around 2 year’s ago? What changed your mind or maybe i cant remember correctly?
I remember slightly where several people in this forum could easily lost their files, where a partition mistake happen and no one could help him in this forum.
That some snapshots because of BTRFS are weaker than Rsync. And additional the BTRFS snapshot’s was very difficult to rollback in some cases.
I remember also a guide from yourself, where you point in one of your help topic’s… what for additional steps the BTRFS user has to do if he don’t use ext4, when he run into errors that he have to fight first the BTRFS hurdle.
Are this con’s are all history? Then maybe my viewpoint are total outdated about the dangers from BTRFS… that made me evade this filesystem in the past (no matter what). Even if i like the Pro’s and wished that some of them introduced to ext4, like the autochecksum check… which sounds really nice but the write protection for partition looks very confusing… where i don’t know if this is now the BTRFS feature or is my SSD dieing and went into write protection. 
I saw you posted it countless times 
Not alone that i’am a die-hard hardcore gamer and Manjaro is the right distro for me… i also think that Manjaro itself presented himself in a total differend light as you see what Manjaro is or should be.
For exactly this people it worried me this BTRFS changes… and yeah, i remember when i did this pacnew changes 2 year’s ago.
But in which errors did this unexperienced people run from their unmaintend pacnew files? Nothing that comes close as a BTRFS Partition… where you can face a horror case if you use it blindly… and this won’t happend with ext4.
I think that ext4 is much more consumer friendly.
