1) It doesn't allow a web app to ask for a storage allocation up front, before it starts to consume the storage.
Why does that matter?
2) In Opera, the quota can only be increased in multiples of about 15, so it takes three prompts to get up into the range of gigabytes.
But there is an unlimited option, yeah?
These all feel like user-agent specific worries on how the user agent wants to bring this to the attention of the user.3) The web app can't choose when the question is put to the user. 4) The web app doesn't know how much storage has been allocated, so it doesn't know when a question will be asked. 5) In Opera, if the user chooses "Reject", they don't get prompted again. This means that asking the user at an appropriate time is important for the continued functioning of the web app. Prompting the user at the wrong time will interrupt them with a page-modal dialog which they might want to get rid of with "Reject", which would potentially break the web app by leaving it unable to get more storage.
