It is good that people are trying. In the last more than 3 years there have been a lot of suggestions of "non-flush" flushes and you never hear from them anymore. One time suggestions and nothing happens. I find the same about this idea that it can't replace the flush, but the only way to find out is people try it and report back.
Everybody would like to find an easy way out and if there was one everybody would have been doing this for years. Even the egg thing is an old suggestion.
The only person so far that had success ended up putting the egg yolks in the olive oil and it became a regular flush again.
