Short answer: it will probably work

Long answer:
In many cases these "old" extensions simply work in 6.2. Quite often 
you'll see Fatal PHP errors because of require/include(_once) statements 
which weren't necessary with 4.3 and later, but which have to be removed 
in 6.2.

For an extension which only adds new fields to a table it would be nice 
to move the TCA manipulation to 
/Configuration/TCA/Overrides/fe_users.php This way the TCA will be cached.
It's not absolutely necessary to do this to get your extension working 
in 6.2
