The github page of the package mentions the following:

> The size of storage is typically limited to 16 kilobytes. This applies in browser and in Arcade devices. Smaller MCUs may limit it further (eg., it’s 1k on SAMD21 devices).

I don’t think so, otherwise I would expect this function would need to be part of  
[settings.ts](https://github.com/microsoft/pxt-common-packages/blob/master/libs/settings/settings.ts) of this package.
