I'm going on about the idea of maintenance items should be readily accessible, rather than requiring partial or total disassembly of the unit being maintained. Burying maintenance items is what happens when you let accountants, lawyers, and exterior designers get involved in engineering decisions - engineers are, by nature, lazy; and will therefore design things with that idea in mind (or the idea that they themselves are going to have to maintain the thing, which is much the same.)
It's a variation on how I select materials, select replacement parts, and design things - I do so with the assumption that the next poor schmuck to work on it will be me, I'll be standing up in a hammock, and all I'll have will be a Gerber Multi-Plier and a Swisschamp Swiss Army Knife (neither of which I'm without if I go over my property lines.) MacGyver ain't got a damn thing on me...
