Summary and Motivation
Deprecate and remove -webkit-font-size-delta[1], Because the usage of this property is low[2]
And this property is non-standard[3].
On the basis of the above, we make this intent to remove this property.

CL by HyunJi Kim : https://chromium-review.googlesource.com/c/chromium/src/+/2358723

Interoperability and Compatibility Risk
Firefox: Not supported
Webkit: supported

Alternative implementation suggestion for web developers
Use the 'font-size', because  '-webkit-font-size-delta' is currently being overridden[4] if 'font-size' is specified.

Usage information from UseCounter
The usage is estimated as 0.007%[2]

This seems similar to https://groups.google.com/a/chromium.org/forum/#!msg/blink-dev/p1D2Fj8WTe0/p6uQY-oACAAJ only requesting for removal as well.

As we already started discussing removal on the other thread, I suggest we'd ignore this one as a duplicate.
