It is still the same installation method, directly installing the .apk file, from way back when the term for Android usage was defined. So, kinda, but also kinda not.
Also, if you do use ADB to do the install from a PC, the command is “ADB sideload filename” which will do the transfer and installation to the memory directly. Then it truly is sideloading as defined.
Android doesn’t use ROMs (Read-only Memory) any more either, because the filesystems are now writable. But Lineage etc are still called custom ROMs, because the end result hasn’t changed.
