The best chance to get real 1w green laser.

The diode has a ball lens, intended for fiber coupling. hence the poor divergence factor. I avoid diodes with built in ball lenses.

That nobody bothers is a business decision--probably because it would have no effect on sales and just be another thing to worry about building, stocking and warrantying, would not sell well if at all, and be expensive to do.
Is a small niche within a small niche within a micro-niche market --not many people know enough to consider the questions much less purchase an answer.
Even on LPF there are what 3 or 4 people that care enough to want to play with cylinder pairs, beam correction, and beam expanders for correcting the nature of laser diodes not intended for or designed by the diode makers for use in hand held lasers.

There's also the liability aspect of this issue. Sure, Sanwu could put corrective optics into one of their handhelds, but putting lasers out into the wild that have the power and low divergence to accidentally blind someone from a large distance puts the company in a bad position legally. They, of course, would claim, "We just built the laser. We're not responsible for how it gets used" But if the laser is legally in a grey area as most of Sanwu's are in this country then it could cost them a lot to make that defense work.

I don't think anyone has successfully sued anyone in China from outside that country. It is also why they don't mind breaking the law here by importing laser pointers over 5 mW. You really can't go after them.

They aren't breaking any US importation law. They are exporting/exporters. The persons breaking US law are all the persons purchasing then importing said lasers who live in the US.

There's no liability. They are a company based in a sovereign country and not subject to US federal law.

Lasers are essentially used in marking targets, guiding munitions, hashtag#missile hashtag#defense, Electro-Optical Counter Measures (EOCM), and blinding troops. The laser has applications in most of the firearms and can be used as a tool to enhance the targeting capacity of another weapon system
