| Limitation | Consequence | | :--- | :--- | | Fixed component set | Cannot add more modules (e.g., Qt WebEngine, Qt Virtual Keyboard) without online maintenance tool. | | No minor updates | To patch from 6.5.1 → 6.5.2, you must download the new full installer. | | Larger initial download | ~2 GB vs ~40 MB for the online bootstrapper. | | Less frequent releases | Not all patch releases have corresponding offline installers. | | Target-specific | One installer → one host platform + one target compiler. |
