I believe there are good reasons to play Flannery. These may not balance the downside of losing a weak 2D, but the reasons remain valid either way.
1. Playing 2/1 and holding 45 shape in the majors is awkward unless the hand has reversing values. Flannery avoids all the rebid issues after !NT and even 2C or 2D bids. Now the 2S bid is a reverse and there is no doubt. Furthermore, when you have 4513, 5431 or 5422, the rebid over 1NT forcing is a disaster. 2H is probably best except maybe with 5413. But that is a big problem because the 2H bid really needs to promise 6 cards if partner has any hope to evaluate his invitational hands.
2. With Flannery, it is possible to play 1S response as guarantees 5+ Once again, this makes things a lot easier when it comes to evaluation of hands.
3. Flannery also comes with a decent set of tools for exploration of slams and even making wise decisions about game.
4. Competing with a Flannery opener is on the awkward side. Penalty doubles are pretty easy to find if your decision to compete is wrong because opener's hand is so clearly defined. After all, you most likely will be deciding which minor to play in at the 3 level in an auction where fit is totally unknown.
5. Against weak players or unfamiliar partnerships, simply knowing what the defensive calls mean is not clear. This can lead to a total train-wreck by your opponents.
There is a reason that hardly any world-class pair plays Flannery, and very few expert players use it. You give up more than you get.
What do you get? The ability to show 45 hands with 11-14 HCP more easily. It's not that big a benefit. First off, those hands don't come up that often. Second, when they do, you generally are OK opening 1H. If the opponents compete, partner has a negative double available. If partner bids 1NT, he doesn't have 4S, anyway. If partner bids 2 of a minor, you have a game force and can find your spade fit later.
The only real benefit comes when you are specifically 4522 and have to bid a two-card club suit after 1NT forcing. Big whoop. Flannery is a solution for a problem that really isn't all that bad.
Yes, low-level players may have difficulty bidding after an opposing 2D Flannery opening, but for more experienced players, it is probably easier competing vs Flannery that vs a standard 1H bid, because you know precisely what that player has.
What do you give up?
1. The weak 2D bid (or Meckwell or Wilkosz or whatever you like)
2. If the opponents buy the hand, they will be able to play it more or less double-dummy (you have just told them your shape and HCP count)
3. If the 2D opener becomes dummy (which does happen sometimes after asking bids), the opponents will be able to defend pretty much double-dummy
That's way too much for the marginal benefit.
