actually not enough work was spent in a timely manner to provide the corresponding tooling so this is inaccurate.
Honestly, the tooling was lacking. much of this was discussed in the NU5 retrospective meeting for which I can’t find a link for at this very moment. If someone can provide that for me I will appreciate it
ps: if you are asking “why was that?” the answer is “sandblasting”
ps2: the thread on the retro NU5 and Sandblasting retrospective - #2 by aphelionz thanks anonymous Zcasher who sent me the link
