[RAC] prevent date picker onChange firing prematurely

[binaryartifex]

i have a dashboard broken up into several charts, each chart has a date picker in the header to select a date to fetch data for. for keyboard users, the onchange starts firing when the first number of the year is set and each subsequent number until all four characters are input. now i understand that '1' is technically a valid year, but is there a way to delay the onchange from firing until either all 4 year characters are input? im losing my mind trying to stop my api endpoints being hit with three ridiculous date times before it finally settles on the proper one.

even if folks are either ideologically opposed to this idea or it just can't currently be done, is it possible to at the least, make the segments read only to encourage (force) users to use the calendar? i discussed this over at #6188
