It is a commonly used quick and dirty fix when you don't have a purpose-built grommet to install in a rim cut for a Schrader valve. It may also not be a terrible idea if, for whatever reason, your Presta-hole rim has a burr or sharp edge and you want to avoid any possibility of problems with that.

No, there is no reason for that type of installation unless the whole in the rim is sized for a Schrader valve, rather than a presta valve. It is, as you found, unlikely to cause an issue though.

When a rim is extruded, the shape of the material can give added strength to the rim. There are many rim types, but the two most common are single-walled and double walled. A single walled rim uses a simple U shaped extrusion. A double-walled rim adds a cross brace across that U shape, creating a D-shaped extrusion. Triple hollow construction add extra ...

A rim is a piece of aluminum extrusion, rolled and joined into a hoop. There are several types of joints used. Rims can be pinned together using a piece of metal at the seam to hold the alignment. Or the seam can be aligned and welded. This is the strongest method. Welded rims used to have a small bump at the seam from the welding process, which would ...

The specific handling changes you will get come from two effects. First, lowering the front puts your weight further forward, and tilts your torso down. You'll find the bike tends to "dig in" more then you go down into a dip or rut, and you're more likely to go over the handlebars as a result. You'll also have more weight on your arms, so you're likely to ...

700c and 29" and ISO 622 wheels are the same rim size (typically ones marketed as 29" are wider than ones marketed as 700c, so you can run fatter tires), so if you can go with that, thats what I'd do. Most front wheels are 100 mm hubs, so the wheel will go in. With rim brakes, the brakes won't align (and you'll have to remove them, since you don't care ...

You don't have to replace it with the exact same rim. Your wheel doesn't appear to be anything exotic, so anything with the same diameter (700/622 bsd) and the same number of spokes (20?) should be compatible. You'll also probably want to look for something that is about the same width, although you can make small changes to this depending on your needs and ...
