Yes, the more are able to install it the better,

but figuring something out again still means means you first need to own or having access to a Windows machine or it’s not the really legal way ... in some point (at least for downloading) a Windows tool will be evolved what means you need to install it what implements the access to a legal Windows copy (even if installed in a virtual machine or in boot camp you need a legal license ...)

And you can’t just download one image and give it to community as it will be individual purchases and you will have to download your own copy ... - however Jolla ans Sony plan to make this happen (hopefully not with any kind of drm) it would be illegal to spread it

So back to the first statement. The more the better - I’m pretty sure the point won’t be the availability of a Windows tool but unlocking the bootloader plus saving the drm keys - Just imagine the shitstorm that will go down on Jolla when crowds of “only wanted to try it” people realise that they don’t get back their Sony-extra-stuff when flashing back to android ... - or even more likely don’t get the unlocking process anyway and you can read everywhere about the shitty OS you can’t even install or that bricked your device or ...

I don’t know what Sony an Jolla a brewing together right now, but as long as bootloader, adb tools, fastboot and other stuff are evolved I would highly recommend to keep the flashing process advances as you don’t want any noobs to brick their devices and spreading bad news ... at least you need a really good and fast support hotline - have a look at the Fairphone forum and you will realise how many things can go wrong even without having to downgrade, unlock first

just my point of view
