Yes, my request is to do it like brouter-web and dynamically parse and display all parameters from brf file.
I don't have a specific request for confirmed parameters, despite maybe the kinematic model parameters (totalMass, Maxspeed etc.), which are brouter-builtin.
All other parameters I would like to use mostly exist in single profiles only and therefor I wouldn't recommend adding them as supported to Locus just because of this one profile.
For example, I created an enduro-motorcycle profile on user-request which has a "non-standard" parameter to switch the avoidance of paths, or I consider adding another parameter to influence uphill routing on paths to my mtb profile etc...). Without support for generic parameters, I would have to generate separate profiles of all permutations of profile parameters like libor does, but it gets confusing and it's not easily switcheable for example in a routeplanner session (if the profile-variants aren't already assigned to the (limited) slots in Locus).
As I wrote before, I think it's ok that the default setting only shows the whitelisted parameters (as is now).
But I would like to have the possibility to enable "full dynamic parameter" mode in expert settings for power-users (which you clearly embrace with locus (intens, url favourites, bt-buttons, dashboards, quick pois, presets...should I go on with the list?

)).
Maybe you could group the whitelisted parameters at the top of the settings dialog and show the other "non-standard" parameters below. Maybe with a caption "additional settings" and in a fainter color?
