I would’ve not use nullable. 

I would change the pattern to be “10 upper-lower or null”  I’m not sure {0,10} would be what you want.

Indeed, I do prefer to use a pattern only
For example:

username:
   type: string
   pattern: "^[a-zA-Z]{0,10}$"
   example: John

 or this one:

username:
  type: string
  pattern: "^[a-zA-Z]{10}$|^$"
  example: John

 

In any cases, "nullable: true" seems to interact quiet differently, depending on the other keywords (see this post and this one for more details). 

So my question is: in which case,  "nullable: true" is the most appropriate?
