There’s no real management involved. I set up a wildcard MX record for *.example.com and hand out jim@<some-id>.example.com whenever anything needs my email address. I don’t need to specifically set up an alias. If spam comes in, I look at the To address to determine where they obtained my email address. Fastmail can be configured this way, for instance.
Most mail providers also support plus addresses or wildcard local parts, so you can do jim+<some-id>@example.com or just <some-id>@example.com. Gmail supports plus addresses, for instance. The downside is that some services reject pluses and some spammers strip out the IDs.
