TCA Overrides has wrong extension order

Description
In TYPO3 6.2.12 it sometimes happens that the TCA Overrides do not work. The table TCA of the original extension is not available at the moment, when it should be overridden. The constraints have been set in the file ext_emconf.php.
'constraints' => array(
'depends' => array(
'typo3' => '6.2.0-6.2.99',
'tt_products' => '2.11.0-2.11.99',
),
$GLOBALS['TCA']['tt_products'] remains completely unset in the file tt_products_extended/Configuration/TCA/Overrides/tt_products.php.
Therefore the new fields are never added.
init.php 56 loadExtensionTables
Bootstrap.php 943 loadBaseTca
ExtensionManagementUtility.php 1615 buildBaseTcaFromSingleFiles
ExtensionManagementUtility.php 1674 require
tt_products.php 426 debug
I have followed the steps in
http://docs.typo3.org/typo3cms/TCAReference/ExtendingTca/StoringChanges/Index.html
TYPO3 offers no method to change the order how the extensions are called.

The same error happens occasionally with the file ext_tables.php. The $TCA of tt_products is not loaded yet at the moment when ext_tables.php of the extending extension is beeing executed.
Bootstrap.php 944 loadExtTables
ExtensionManagementUtility.php 1748 requireOnce
PhpFrontend.php 72 requireOnce
SimpleFileBackend.php 364 require_once
ext_tables_52f0fa917869c981191dc1c46475a27420794828.php 3604 debug
So it is necessary to have a sure method to define the order in which the extensions are executed.
I have seen the issue #57825. However it is not understandable why 'suggests' is used for this case. Most users do not understand what 'suggests' means. Many think that those extensions are also required. A new concept should base on a new configuration 'extends'. It does not require or suggest that extension. So the EM will not show it to avoid confusion. 'required' is against usability, because you cannot deinstall an extension if ten other extensions require it. Then you must first deinstall the the other extensions before you can deinstall the required extension. The EM does not support a multiple deinstall and reinstall.

The wording 'suggests' is frequently used among package handling systems. i think we'll keep it. Both 'requires' and 'suggests' can be used nowadays to have an effect on load order, so that should be fine. Wouter also gave the hint that tca defined via ext_tables and other tca defined in overrides may collide, so this stuff should be kept an eye on.
At the moment i can see no core issue here and will close the issue. Please re-open in case you see actually a bug in there.
This is however a bad solution to enforce to set the 'suggested extensions'. User do not understand this. And it may happend that the extension list gets very long. And most of the users will click on every checkbox. And developers will not find this hidden feature anyways.
