The issue is not the number of letters/symbols in an alphabet.
The issue is not the amount of white space on a page.
The issue is all about clarity of communication.

Symbols that increase clarity or reduce the potential for confusion are good.
Symbols that are there based merely on form or tradition do neither.

The additional i does nothing for Aluminium.
The additional u does nothing for Colour, Behaviour et.al.

Tongue firmly in cheek.

By the way, Surveyors have been using a decimal scale for hundreds of years (since 1620) - the Chain Scale. In the US, the Ramsden Scale (1785) divided feet into 10ths, and Chain Scale tapes are still used by surveyors to this day -those not using GPS devices, that is. Note that most surveyor measurements are in decimals.

Ain't history fun?
