I agree, it's not meant for permanent circuits.

That is true and by that time, I have create a soldered version on stripboard that
is functional.  I always create the stripboard version with new parts without
disassembling the SBB version.  That way, I have an easy way to compare
measurements if things don't work as expected.

You lost me here.  I copy the work to stripboard after proof of concept testing on
SBB.  I see nothing lost, I still have a working, but now permanent prototype copy
of my circuit.

I'm unsure of what you're expressing here - that recycling parts is good - or bad?
 Or neither?  Regardless, I don't see this as an SBB disadvantage.
