It's called an acceptable compromise, by those that use it most.

Just like FPC doesn't do micro code optimizations on each and every
platform. The FPC performance [see Martin Schriebers annual posts
about FPC speed vs Delphi 7] hit is a compromise for easier
maintainability of source code. A simple trade-off.

The Maths unit is known for more advanced math and statistical
features. A strong random number generator seem a good fit for that
unit.
