That said, this wasn't directly a cost-saving exercise for us. That's just a nice by-product.
Self-hosted solutions requires maintenance even if you don't anticipate it. It's not "just PHP". It feels like a zero cost (you have got the spare capacity server after all), but only until you hit a problem.
Of course there's a chance that it'll involve a bit of maintenance at some point, and that'll soak up a bit of my time. My experience with hosted solutions is that they have far more frequent hosting issues resulting in lack of access to data (be that scaling problems, being offline for maintenance, bad deploys etc) which soak up lots of time for everyone on the project.
When I'm in control of the situation I know that at least in a bad case scenario I can spin up another server, grab the last good backup and be up and running again within the hour. That has a lot of value.
