QUESTION 1: Will older printers like this stop working soon?
"Printer drivers are deprecated and will stop working in a future version of CUPS"
Nope, they will continue to work, except there is a move towards driverless printing and we're simply not there yet.

QUESTION 2: The ASUS router to which the printer is connected says:
Printer Model: Brother MFC-J450DW
Printing status: Enabled
Monopoly mode: 192.168.50.75
... but I can't get CUPS to see it ... any ideas, please?
Yep, use the right URI when setting up your printer. LPD is for printers connected by USB cable to your machine.
I have found within the last 2 years that the key to attaining success with network attached printers is to always use the ipp protocol when selecting the URI. I have 3 printers, 2 Brother and 1 Epson, all work perfectly ONLY when using the ipp. When I tried other URI's that use some of the fancier protocols, they may have worked for a day, maybe a few, but never for more than that.
First things first, go into your Asus Router and pin the printer to its current IP address. I take this one further by reducing the Routers Dynamic IP Address range by removing the first 20, then pinning all printers and network attached systems that have a specific purpose to use one of the freed IP addresses outside of the dynamic pool. Once a printer is pinned to use a single IP address, I can rest assured I will never have to revisit the printer setup again due to an IP address change.
recommended - Disable the AHAVI daemon which tries to auto-connect and set up your printers, reboot after disabling and you should hopefully have no printers loaded other than those added by driver wizards. Go ahead and remove them all so the screen has none.
Now re-run the Brother script and when it asks will you select the URI, answer yes, then later, when a list of URI's is presented as the script progresses, insert the number that corresponds with IPP or by-ip address and when requested, type in the printers IP address when requested. At the end of the process, your printer and the scanner will work just fine.
This is what it should look like when you're done.
