I remember on xda with my Galaxy S Plus i9001 [1], we had:

- dual boot [2]

- Ubuntu touch [3]

- different kernels with various optimizations, overclocking, etc

- an absurd amount of ROMs, aside from CyanogenMod and LineagesOS there was ParanoidAndroid, Carbon, JellyBean, AICP, plus all the ROMs made specifically by users for this phone

- the latest linux kernel, somebody just compiled it for AOSP, I think it was version 3 or 4 against 2, which was the standard for every other phone, it ended up on some tech news website

I think It was a really great modding scene and a lot of people learnt stuff from that. Mainly by bricking their phones and having to fix them.
