It will always be a trade off between lower signature and protection/awareness.
Active protection systems have radars that will light you up like a Xmas tree, tanks also have a lot of EW gear on them that even before hardkill APS became common used a ton of power and increases their signature.
Silent/LowSig mode is just another tool in their toolkit. If they know that the threat landscape allows them to go into low signature mode safely and that it would improve their combat effectiveness they now will be able to do so.
