@jim m Nope, and I'm a bit concerned by Apple making it much more difficult to get an older installer.
My understanding is that anyone who "purchased" them via App Store download link at the time can still get to them from their Purchased tab in the MAS. But with the caveat the request has to come from a machine running a macOS where the intended download is still installable.
In other words, to re-download an older macOS version installer, I have to request the download from a machine or VM also running an appropriately older macOS version. Fortunately, you can then cancel out of the installer once it launches, and be left with a file you can archive out to media for future use.
