I wonder if we should format the whitespace beforehand (only one propery per line) to make the diffs only contain that one changed line instead of some 20 lines (each time someone wants to change a number).
and then ask Grugnas and borg-, maybe PhyZic and causative for review.

Among the author (temple) and the reviewers (borg-, Grugnas) who will commit that?

Since archers shooting from longer distance have same accuracy as before, the first summary lane is self explanatory and honestly i don't feel the need of a spread increase for such a technology, while i agree that having higher accuracy as reward for promotion is reasonable despite the fact that ranged units doesn't seem to have accuracy issues even at basic rank.

(Just thinking in general, it might be nice to have the tooltips not reference particular values, so that translators wouldn't have to change the strings every time we changed the values. Units have "detailed tooltips" that show their health, attack, armor, etc., so maybe we can do a similar thing with technologies and their modifications. Some players might want to know that the range was increased by exactly 4m, and others players might not.

Sure all that have been discussed since years.
Currently it's done to have values in, so let values in.
It's more or less planed to have automatic modifications tooltip (which has pros and cons, the pro is what you are talking about).

Some technologies have a "description", but I can't find where in the game to see that?)

Nowhere.
I remembered having discussed of that with @s0600204, perhaps it will be included in the whole history thing.
(Same thing sh(c)ould be done for auras)
