inconsistency - why are some properties strict and disallow string while others include (string & {})? #195

We're using css-custom-properties in combination with typescript-design tokens quite heavily for our library. I have found that some properties include (string & {}), while others don't.

Comparing TextDecoration with TextTransform, the latter does not include (string & {}). Same for some other properties like TextWrap, TextRendering, TextJustify ...

Is there any logic as to why every other property supports strings while the others don't?

related to #176

My expectation would be to either include (string & {}) consistently (eg. in the Globals type) or provide some sort of configuration option / different import option to decide whether we want to allow strings or not

removing all types that directly allow (string & {}), or indirectly allow it via for example DataType.Colors, DataType.FontStretchAbsolute, DataType.Position<TLength>, DataType.Dasharray<TLength>

we get 185 types that dont support (string & {}).

as outlined here, there are a few generic types like the one below, that allow any (pixel) string or 0 (unitless).

export type WebkitTextStrokeWidth<TLength = (string & {}) | 0> = | Globals | TLength;

filter out generics that default to (string & {}) and we are left with 146 properties that dont support strings.
