Create visible lock files

Would it be possible for LibreOffice to create visible lock files like AutoCAD does? Dropbox claims it cannot synchronize the hidden lock files that LibreOffice creates because they are done differently on different operating systems.

AutoCAD style:
filename.dwl plain text or xml file identifying locking user

Suggestion:
filename.ods.lok

LibreOffice lock files are plain text files identifying locking user. If there’s some issue you are referring to, then please describe the issue in detail - in bug tracker (also put a link to where Dropbox claims that, or logs, or something), but do not try to suggest a fix to an unidentified issue.
