Comment:
Maybe a middle sentence:
> In addition, MySQL will fully rewrite tables for almost every schema
operation and generally takes a time proportional to the number of rows in
the table to add or remove columns. On slower hardware this can be worse
than a minute per million rows - adding a few columns to a table with just
a few million rows could lock your site up for over ten minutes.
is a bit inaccurate, but you haven't presented any references to prove it.
Also, generally this paragraph is still valid. Closing as "needsinfo" for
now. Feel-free to investigate and provide details what and where is wrong
in docs.
