Oracle implements this using "cartridges".

So if you need Spatial, you get a Spatial cartridge. They also have a
ConText cartridge, and another cartridge for storing pictures.

Given this idea, the Interbase community can implement this using
"cartridge" like UDFs which can be installed if you need spatial functions.

Instead of a Spatial cartridge that you install on top of an Oracle
database, we can develop a UDF module that have spatial functions. Like the
Spatial cartridge, this UDF will be an option and does not need to be
incorporated to the core function.
