Some Advice!

In an interview with one of the new generation guitar 'heroes' that I read little while ago he offered the advice to young guitar players to stick to playing of one style of music. My guess is that he talked about being proficient in whatever style you like and aspire to succeed in, but did it ever come out wrong?
Why, oh why would anyone pigeon-hole themselves to one narrow area of enormously wide field of music and musicianship? If someone really wanted to be a good guitarist, that someone would welcome any chance to be even better at playing through exploring different expressions and techniques present in the motley world of guitar music.

You don't want to be known as "JUST three chords player", do you? Or sound the same in every tune you play, clocking in at the same tempo, using the same chords and progressions? Where is fun in that?
In my humble opinion: the more you delve into different expressions of music ideas and their delivery, the better musician you get to be.

So can or should you use chord progression from, say, gypsy jazz in your shredding tune? Why, yes, of course.
This is why you hear all these new bands on a radio sound just about the same across the board... same sounding guitars, tired ol' chords delivered in the same manner over and over again.
It is certainly much more fun to explore new styles of music and/or guitar, and try to learn something new from it. Your arsenal of guitar tricks and licks will get larger, and you just might discover very cool and very different way of playing and songwriting. Your ear training will also benefit from unknown songs and artists.
Straight to the point: Don't make yourself boring guitar player, you will get bored and your listeners will, too. As in life itself, keep your mind open to new influences and styles - we have enough bore in this world; don't add to it, please.

Mind is like a parachute - it works best when open

The same goes with guitar techniques: if you always flat pick, try to learn some finger or hybrid picking; if you always play electric, distorted guitars, try some acoustic music; find out how classical guitar sounds in your hands... The more, the better; heck! try playing banjo or mandolin; why wouldn't you if it will benefit your guitar playing skills?  In short - feel free to explore wonderfully colourful world of guitars and music. It is intriguing, very useful and fun!

Cheers!
