There are three basic ‘strategies’ for what an alert really means and, hence, what is alertable: 1. what deviates from a certain standard 2. what may differ from opponents’ expectations 3. what is artificial.
Most confusion about what is or should be alertable or not comes down to confusion on the basic strategy. The WBF Alert Policy is based on #3, which I personally think is the best one.

My vote reflects what I would do. My comment, if any, would reflect my tendencies. Here poster asks me to vote about tendencies, the example not withstanding.

I support on three for lack of a satisfactory alternative, as on ♠432 ♥32 ♦KQ432 ♣AQ2. Here, 2♣ is quite satisfactory. (I prefer to play Transfer-Walsh, though, which eliminates the case.)

As I (and many) play over the weak notrump, an immediate 3♣/♦ (or 2♥/♠) is to play and can work preemptively. Invites with a long minor (or major) go through 2♣ as invitational Stayman, followed by 3♣/♦. 1NT-2♦ is game-forcing Stayman.

Invitational minor suit hands occur more frequently over a weak notrump than over a strong one. Reasons are (at least) twofold:
1. Weak, especially mini notrumps usually have a wider range: 9–12 as I play, 10–13 as many play.
2. An invitational minor suit hand opposite a weak notrump will have side strength. That makes it less necessary that the suit be solid between the hands.

A Mixed Raise is one trick weaker than a Limit Raise. Any raise of an overcall – which, as I play, does not promise opening bid values – is one trick stronger than a similar raise of an opening bid. So, if this hand would be a Mixed Raise of a 1♥ opening bid, it is now a preemptive raise.

It helps as cross-imps neither has a datum nor needs one.
(For those who are unfamiliar with cross-imps:) You compare your raw score on a board with that of every other pair that played in the other direction, and convert the difference to imps, much as if playing teams. You average all those imp scores on the board. That is your cross-imp score on the board. No ‘datum’ needed.
Cross-imps is basically simple and straightforward, but it is tedious to compute by hand. That is why butler scoring was invented, which is basically a rough approximation but is easier to compute by hand. With the advent of widespread computing power, butler really has no right of existence any more.
