Where can we post a vsix for testing, where it will get attention and some usage?

Here are the issues that are regressions vs the old parser. Currently, a total of 6 issues:

https://github.com/felixfbecker/php-language-server/issues?q=is%3Aissue+is%3Aopen+label%3ARegression

https://github.com/Microsoft/tolerant-php-parser/issues?q=is%3Aissue+is%3Aopen+label%3Alang-server-regression

I'm not sure whether all of them are blockers?
