How would that work when you need to match a pin type with an external data

In most cases it will just work. Possibly with unused higher-order bits.
Unless anything is _relying_ on overflow, there shouldn't be any
difficult fixes.
Encoders are commonly used in Linuxcnc and do overflow. However not sure
if this i a big problem since it fit inside a double.
Then there is for example a double output a unsigned or signed 16 bit
input to a servo drive there is a problem that must be handled. Same
apply for digital outputs. There will also be a need to map these into
PDOs if using CANopen.
Programmed for many years and it is a lot harder to work with dynamic
unknown data types. Numbers with unknown range is also a little bit
harder to work with and in particular must be some method to handle the
case then number is outside expected or valid range.
