There's your answer right there, no need to ask.

Without human advice and a metric shit-tonne of guidance (either pre or post) - anything that requires active consideration of future maintenance burden will cost you 2x-10x of the time you think "saved" over a medium-term time-frame.

The alternative is to spend at least 50% (or sometimes up to %100) of the "saved" time in active review and iterative improvement of the solution design.
