The GDM724x is removed for supporting the GCT GDM724x LTE chip based USB modem devices. This driver was merged back in 2013 but is being removed now as the driver isn’t being maintained and yields a maintenance workload, the manufacturer GCT doesn’t respond to any emails/support, there doesn’t appear to be any of the said chips easily available for purchase, there is not any hardware documentation available, and no apparent usage of this driver remaining in the Linux community. Removing the driver clears out 3.6k lines of code and lowers the maintenance burden for other kernel developers.
There was also a vulnerability discovered in July linked to this driver.
So yeah I understand that they chose to remove some drivers from the kernel.
