It is the thing that makes sense.

Had been concentrated upon 

(add-hook 'outline-minor-mode 'tika-minor-mode)

which could produce unintended consequences if one wants to activate 
tika-minor-mode 
only when outline-minor-mode is activated.

-------------

For things like

(add-hook 'fortran-mode-hook #'tika-minor-mode)

where I want to enable tika-minor-mode when fortran mode is enabled.  Would you
suggest using a function that checks whether fortran-mode is activated ?
