I know (not really) that golemancy is a mess and very hard to add anything without breaking things but this would be a very cool QoL imporvement.

Not my idea, loaned (stolen from) here: Azanor/thaumcraft-suggestions#332

Like the post it should not give everything back, maybe upgrading the disassembling method would yield better results.

We do have vague plans to add a workbench block for editing golems at the cost of machina essentia (we didn't consider disassembling golems), but since things have been slow lately I can't really say if/when it will be added.

Cool to hear that you've discussed this. Take you all your time with uni/work/whatever, this addon is already the best TC6 addon maybe even the best TC addon overall :D.
