Well, Alpine Linux actually works with backward compat (as glibc can be easily installed) and uses a few dozens MiB of RAM. FWIW, I use Alpine Linux on my pinephone in the form of postmarketOS (an Alpine derivative) with a full-fledged KDE desktop, running Firefox alongside. IOW., you can use it as daily driver just fine, just need to install the respective packages - which naturally makes it use more resources, but even then far from what Windows will use.
