Like the axiomatic approach to geometry, you could refuse to refer to things not yet proven. More people will begin your paper than will reach the end. Try to state results before you prove them. Push off complicated derivations and digressions until the end. Complicated mathematical derivations, especially if marginal to your main thesis, should be relegated to appendices.
Wordy constructions rob the prose of force.
In your paper you might want to include digressions, possible applications, etc. But be sure to include language that labels them as peripheral. If you don't, some people will miss your main point and quibble with these peripheral matters. A technical document rarely has a preface because a preface describes the document itself without describing the material content. For example, if I made a preface to this article it would say that this article previously appeared in a report of the Stanford Exploration Project.
