We take "zhwikisource" to be defined as potentially pertaining to the
entire macrolanguage, and on those grounds reject this request.
This position could impact the establishment of other Chinese languages wikisource in the future, especially those that doesn't use Han characters, or those that utilize a different set of Han characters. Granted there are not much document of those languages in wikisource now and there doesn't seems to be much available content that can be uploaded in the near future as most of these language aren't accustomed to be written out directly instead of translating into Standard Modern/Classical Chinese during the writing process, so most materials would be things like lyrics or speech transcription and such, and that some more recent materials that are beyond these aspects are still subjected to copyright, but as times goes and more material will be eligible to and are being uploaded to wikisource, this might be a problem in project creation for those languages.
Also, another thing to note is that, most Chinese speakers in Greater China area nowadays can understand Literary Chinese text (even if just for a limited extent for most people), probably because almost all schools in the Greater China area teach literary Chinese as part of their language course. It probably helped the current effective management of already uploaded LZH text in Chinese Wikisource. The same couldn't be said to text written in other Chinese variants, especially those that use alternative non-Han scripts like Latin/Arabic/etc scripts.
