About allowing uppercase to table name in V1.7

Question

Now, table name (include prefix) is limited in lowercase. Uppercase may be allowed to the database table in V1.7. I think this change is mistake.

Because ...

1. It becomes incompatible between operating system (Linux, Windows, MacOS, etc), and Q2A becomes none-cross-platform system.
2. WordPress and Drupal convert table name to lowercase at installation.
3. Various problems happen when uppercase is admitted for table name.

   etc, etc
4. As for this change, this thread and this seem to become the basic point. This is issue of specific plugin. And not issue of Q2A core.

How do you think about this?
