The potential (and often actual) problem with your seemingly-reasonable position is that "passing the tests" is not always a good indicator of whether women are suitable to the job or not, because the tests often have biases (whether overt or implicit) that disadvantage women.
For example, in the traditionally male trades (construction, machinery repair, etc.) the "new guy" is often stuck with the job of doing heavy lifting/carrying that the veterans CAN do, but don't want to do. So an apprentice carpenter spends his/her day at the job site schlepping heavy loads of lumber around. That particular "skill" is almost irrelevant to the actual job of being a carpenter (putting those pieces of wood together in useful ways). This sort of "pledge, wash my car..." hazing can discourage women who might otherwise make excellent tradesmen tradespeople.
Another example is from, of all places, orchestral music. Orchestras learned they had to audition potential players behind opaque screens because evaluators often had (frequently subconscious) biases about which instruments were "male" or "female." Hence, they would discount excellent performances by players who were playing the "wrong-gender" instrument and elevate their evaluation when the player's sex matched their bias about the instrument's "gender."
Sometimes, being the "wrong" sex is a profession has advantages. I heard a radio interview with a female jet aircraft mechanic who said her colleagues often called upon her to help, because her small body and slender arms could get into nooks and crannies that her big beefy coworkers had trouble reaching. Or consider the nursing profession, which is dominated by women, but where being a big strong guy is probably very helpful when you need to physically lift/move a patient.
So, yes, standards are good. But we need to be careful those standards actually relate logically to the job and that they don't include biases which needlessly disadvantage one sex or the other.
