Summary
Rationale
We use String columns as the physical storage for many kinds of logical datatypes, whether it's a UUID as String(36), IPAddress as String(39), or generic strings which are usually String(255).
Right now, the standard is for developers to use SQLAlchemy's String type directly, where they pass in the desired length.
There are a few problems with this approach:
1. Cumbersome - it requires the developer to specify the exact length each time they a new string column. In most cases, you just want the 'standard' size, so you look around, decide that 255 is most common, and use that.
