    IMHO, you are confusing two very different things here:

    1) Assigning arbitrary glyphs to some Unicode characters. E.g., assigning
    the "$" character to long S; the ASCII letters to Greek letters; the whole
    Latin-1 range to Devanagari characters, etc.

    2) Choosing strange or unorthodox glyph variants for some Unicode
    characters.

    The "hacked fonts" you mention are case (1); what is being discussed in this
    thread is case (2). Like it or not, superscript e *is* the same diacritic
    that later become "Ę", so there is absolutely no violation of the Unicode
    standard. Of course, this only applies German.

    The fact that umlaut and dieresis have been unified in Unicode, makes such a
    variant glyph only applicable to a font targeted to German. You could not
    use that font to, e.g., typeset English or French, because the "Ę" in
    "co÷peration" or "na´ve" is a dieresis, not an umlaut sign.

    There are other cases out there of Unicode fonts suitable for Chinese but
    not Japanese, Italian but not Polish, Arabic but not Urdu, etc. Why should
    a Unicode font suitable for German but not for English be any worse?
