Note that the text color variable from the color theme (that seems to be what was used previously for this) is consistent with the color theme in the sense that it's a valid foreground color for the context where this date is displayed (on the page background).
An "inconsistent with color theme" would be something that is hardcoded, or for which the background color is not ensured, risking resulting in contrast issues for some color themes.
Link color is also a valid foreground color for that context, so, for me this issue is more of an improvement than a bug, based on a choice of style (which, again, is perfectly valid).
