Perhaps. PbLua was and is an act of passion that seems to deserve a separate designation. :) 

Lego opened up the sdk and put a "real" computer in ther, complete with a bootable SD slot. They also expressly hoped that by open sourcing the brains, they'd see a community of developers step forward and play. 

A search for "Lego ev3" on github shows that their strategy worked.
