Strongly agree. I would take it one step further, consider this line:

You should def try to commercialize your slop and get feedback. No one cares about your tech stack or whether it's maintainable. Does it add value? You'll get a strong signal as to whether it does or not. And adding value, picking the right problem in the right domain, that's the hard part. You can always re-write or clean it up. Didn't Javascript start out as a weekend project? (maybe not a great example depending on how much you like JS)
